Customers were encouraged to purchase the charm individually or to build a ready-to-wear piece with James Avery’s Hook-On Bracelet or Changeable Charm Holder Necklace, officials said.

"The charm represents a partnership between two legendary Texas brands that both got their start in the 1950s," the release states. "In the summer of 1950, one man with a dream opened up a small burger stand in Corpus Christi that would eventually turn into the orange-and-white striped restaurants we know and love."
